SPECIFICATION forming part of Letters Patent No. 430,342, dated June 17, 1890.

Application filed December 30, 1887. Serial No. 259,382. (No model.)

To aZZ whom it may concern.-

Be it known that I, LINCOLN HAUSMAN N, of the city, county, and State of New York, have invented a new and Improved Rotary Engine, of which the followingis a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a broken side elevation of my new and improved rotary engine; and Fig. 2 is a transverse sectional elevation of the same, taken on the line as x of Fig. 1.

The invention. will first be described in and then pointed out in the claims.

A represents an annular steam-chest made, by preference, of a tube formed with a slot B at its periphery. In this slot is fitted the inner edge of the annular plate or disk 0. Secured to the inner edge of this disk is a piston-head D, which fits the circular cavity of the steam-chest A, as shown clearly in Fig. 2, so that when steam is admitted to the steam-chest through induction-pipe E the said piston and annular disk 0 will be forced around the steam-chest A. That portion of the annular disk 0 which enters the slot B and the'surfaces of said slot are correspondingly corrugated to prevent the escape of steam. The exhaust of steam from the steamchest is through the pipe E or E", according to the direct-ion of motion required. Between the said two pipes E E is fitted in the chest A the sliding valve or cut-off plate F, fitted in a transverse slot or opening F. This valve or plate is operated out and in by two levers ,G G, fulcruined, respectively, in the arms H H. The lower end of the lever G is connected to the short arm of the lever G by the connecting-rod J, and the long arm of the said lever G is connected to the'plate F by the connecting-rod J. The upper end of the lever G is bent over to stand near the annular disk 0, and on said disk, nearly in line with the piston-head D, is formed the cam K, which is adapted to strike the upper end of the lever G just before the piston head D reaches the valve F, and force said upper end of the lever outward and cause lever G to draw the valve F outward and allow the piston-head to pass and permit the exhaust. After the piston-head D has passed the valve F the said valve is returned by the action of the spring L. (Shown in Fig. 2.)

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. The annular steam-chest A, slotted at B, the annular disk 0, fitted in said slot, the piston-head D, attached to the annular disk, and the valve F, in combination with the levers G G, connecting-rods J J, and the cam K, formed on the disk 0, substantially as and for the purposes set forth.

2. The annular steam-chest A, slotted at B around its periphery, and slotted at F, in combination with the annular disk 0, pistonhead D, and cut-off Valve F, substantially as described.
